Power Management

Your notebook has many options and features for conserving battery power. Some are automatic and need no user intervention. However, others depend on parameters you set to best suit your operating conditions, such as those for the display brightness. Internal power management can be controlled by settings made in the operating system, power management application, or settings made in BIOS setup utility.

Besides the options available for conserving battery power, there are also some things that you can do to prevent your battery from running down as quickly. For example, you can create an appropriate power saving profile, put your notebook into Sleep mode when it is not performing an operation, and you can limit the use of high power devices. As with all mobile, battery powered computers, there is a trade-off between performance and power savings.

Power/Suspend/Resume Button

When your notebook is active, the Power/Suspend/Resume button can be used to manually put the notebook into Sleep mode. Push the Power/Suspend/Resume button when the notebook is active, but not actively accessing anything, and immediately release the button. Note that if you press the button continuously for four seconds or longer, your notebook will shut down.

If your notebook is suspended, pushing the Power/Suspend/Resume button returns your notebook to active operation. You can tell whether the system is Suspended by looking at the Power indicator. If the indicator is visible and not flashing, your notebook is fully operational. If the indicator is visible and flashing, your notebook is in Sleep mode. If the indicator is not visible, the power is off or your notebook is in Hibernation mode. (See Hibernation Feature)

Sleep Mode

Sleep mode in Windows saves the contents of your system memory during periods of inactivity by maintaining power to critical parts. This mode turns off the CPU, display, hard drive, and all other internal components except those necessary to maintain system memory and for restarting.

Your notebook will go into Sleep mode due to one of the following actions or conditions:

•Pressing the Power/Suspend/Resume button when your system is turned on.

•Selecting Sleep from the Windows Shut Down menu.

•Timing out from lack of activity.
